Description

Technical Field

[0001] This application relates to the field of walls, and more particularly to a soundproof wall. Background Technology

[0002] In modern architecture, soundproof walls are an important component, widely used in residential homes, commercial buildings, industrial plants, and professional recording studios. Existing soundproof walls mainly rely on the combination of physical materials and structural design to block and absorb sound waves and reduce noise transmission. However, with social development and the improvement of people's quality of life, higher requirements are placed on the performance of soundproof walls, especially in places that require high sound absorption, such as recording studios, concert halls, and high-end conference rooms.

[0003] To achieve high sound absorption, various solutions have been employed in existing technologies. For example, multi-layer composite materials, including combinations of sound-absorbing panels, sound-insulating felt, and hollow layers, are used. These solutions typically form a complex damping and sound-absorbing system by layering materials of different densities and thicknesses, thereby effectively absorbing and isolating sound waves. In addition, advanced materials such as high-density fiber materials, honeycomb structure materials, and porous structure materials are used to further improve the sound insulation effect. However, these solutions still have some limitations in practical applications, such as complex installation, high cost, and material aging.

[0004] According to patent document "CN 210621999 U", while existing soundproof walls on the market can provide a certain level of sound insulation, they still have significant shortcomings in applications requiring high sound absorption standards, such as recording studios. Firstly, the structural design of existing soundproof walls is relatively simple, failing to fully utilize the characteristics of different materials to achieve optimal sound absorption. Secondly, traditional soundproof walls often struggle to simultaneously isolate low-frequency and high-frequency noise in complex acoustic environments, resulting in insufficient overall sound insulation performance. Furthermore, existing soundproof walls lack innovation in material selection and combination, failing to effectively address the problems of material aging and performance degradation during long-term use. Therefore, to address these shortcomings, there is an urgent need for an improved soundproof wall system that can be applied in high-sound-absorption environments to meet market demands.

[0022] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] An embodiment of this application provides a soundproof wall structure, which is a sandwich wall structure, including a base layer and a soundproof layer. The soundproof layer includes a sponge layer, a glass layer, a hollow layer and a foam layer arranged in sequence. The surface of the sponge layer faces the interior, the surface of the glass layer is tightly attached to and fixedly connected to the back of the sponge layer, the surface of the hollow layer is tightly attached to and fixedly connected to the back of the glass layer, the surface of the foam layer is tightly attached to and fixedly connected to the back of the hollow layer, and the back of the foam layer is fixedly connected to the base layer.

[0025] The following is in conjunction with the appendix Figure 1-3This application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other. One embodiment of this application provides a soundproof wall 1, which is a sandwich wall structure, including a base layer 2 and a sound insulation layer 3. The sound insulation layer 3 includes a sponge layer 4, a glass layer 5, a hollow layer 6, and a foam layer 7 arranged sequentially. The surface of the sponge layer 4 faces the interior, the surface of the glass layer 5 is tightly attached to and fixedly connected to the back of the sponge layer 4, the surface of the hollow layer 6 is tightly attached to and fixedly connected to the back of the glass layer 5, and the surface of the foam layer 7 is tightly attached to and fixedly connected to the back of the hollow layer 6. The back of the foam layer 7 is fixedly connected to the base layer 2.

[0026] Specifically, the sandwich wall structure forms a comprehensive sound insulation system through the sandwich design of multiple materials, which can effectively block sound waves of different frequencies and enhance the overall sound insulation performance; the base layer 2 serves as the basic structure of the sound insulation wall 1, providing support and stability, and ensuring the overall strength and durability of the wall; the sponge layer 4, as the first layer of the sound insulation layer 3, faces the interior and is mainly responsible for absorbing the sound waves in the room. Because the sponge layer 4 has a porous structure, it can effectively absorb and scatter sound waves, reducing noise reflection and propagation. The glass layer 5 is tightly attached to and fixedly connected to the back of the sponge layer 4, serving as the second layer of the sound insulation layer 3. The glass layer 5 has high density and hardness, which can effectively block the transmission of sound waves and enhance the structural strength of the wall. The hollow layer 6 is tightly attached to and fixedly connected to the back of the glass layer 5, serving as the third layer of the sound insulation layer 3. The hollow layer 6 forms an air sound insulation strip, utilizing the low sound transmission properties of air to further block the transmission of sound waves. The foam layer 7 is tightly attached to and fixedly connected to the back of the hollow layer 6, serving as the fourth layer of the sound insulation layer 3. The foam layer 7 has good sound absorption properties, which can absorb residual sound waves and further improve the sound insulation effect. The fixed connection ensures that the materials of each layer are tightly bonded, forming a complete sound insulation system, preventing gaps between the sound insulation layers 3, and ensuring the continuity and stability of the sound insulation performance.

[0027] Furthermore, when sound waves enter the room from the outside, they are first absorbed and scattered by the sponge layer 4, reducing the direct reflection of sound waves. After being absorbed by the sponge layer 4, the sound waves are transmitted to the glass layer 5. Due to its high density, the glass layer 5 further blocks the transmission of sound waves. The remaining sound waves are transmitted to the hollow layer 6. The air-insulating strip in the hollow layer 6 utilizes the low sound transmission properties of air to effectively block the further transmission of sound waves. The sound waves after passing through the hollow layer 6 are transmitted to the foam layer 7. The foam layer 7 can absorb the residual sound waves and reduce the transmission of noise. Finally, the sound waves, after being treated with multiple layers of sound insulation, are transmitted to the base layer 2. The base layer 2 provides support and stability. At the same time, through the multi-layer design of the sound insulation layer 3, the noise entering the room is significantly reduced.

[0028] In a specific example, the soundproof wall 1 has an inner wall 8 located indoors and an outer wall 9 located outdoors. One end of the inner wall 8 is fixedly connected to the surface of the sponge layer 4, and the other end of the inner wall 8 is exposed and faces indoors. One end of the outer wall 9 is fixedly connected to the base layer 2, and the other end of the outer wall 9 is exposed and faces outdoors.

[0029] Specifically, the outer wall 9 divides the soundproof wall 1 into an inner wall 8 and an outer wall 9, which are used for indoor and outdoor sound insulation respectively. By separating the inner wall 8 and the outer wall 9, it is possible to more effectively block external noise from entering the room and prevent indoor noise from escaping, resulting in better two-way sound insulation. One end of the inner wall 8 is fixedly connected to the surface of the sponge layer 4. This fixed connection ensures that the sponge layer 4 can effectively absorb indoor sound waves and reduce noise reflection and transmission. The other end of the inner wall 8 is exposed to the indoor environment, ensuring that the inner wall 8 can directly contact the indoor sound waves and improve the sound absorption effect. One end of the outer wall 9 is fixedly connected to the base layer 2 of the soundproof wall 1. This fixed connection ensures the stability and sound insulation effect of the outer wall 9 and prevents external noise from entering the room. The other end of the outer wall 9 is exposed to the outdoor environment, ensuring that the outer wall 9 can directly contact the external sound waves and improve the sound insulation effect, reducing the transmission of external noise.

[0030] In a specific example, the base layer 2 has an outer end face 10 facing the outside and an inner end face 11 facing the inside. The inner end face 11 is fixedly connected to the back of the foam layer 7, and the outer end face 10 is fixedly connected to the back of the exterior wall 9 facing the inside.

[0031] Specifically, the base layer 2 is divided into an outer end face 10 facing the outside and an inner end face 11 facing the inside, forming a complete sound insulation structure. This clarifies the two different functional end faces of the base layer 2, making the structure of the sound insulation wall 1 clearer and facilitating the effective configuration and construction of materials. The inner end face 11 of the base layer 2 is fixedly connected to the back of the foam layer 7. This fixed connection ensures the stability of the foam layer 7, enhances the overall strength of the sound insulation layer 3, prevents the foam layer 7 from falling off due to vibration or other external forces, and improves the sound insulation effect. The outer end face 10 of the base layer 2 is fixedly connected to the end face of the exterior wall 9 facing away from the inside. This connection method ensures the stability and sound insulation effect of the exterior wall 9, while increasing the overall strength of the wall and preventing external noise from entering the room through the exterior wall 9.

[0032] In one specific example, the exposed surface of the inner wall 8 is a plane formed by a series of wedge-shaped structures 12 arranged in sequence.

[0033] Specifically, the wedge structure 12 can increase the sound absorption area and sound absorption effect of the inner wall 8 surface. The wedge structure 12 has a large surface area, which helps to absorb more sound waves, reduce sound reflection and transmission, and enhance sound insulation performance.

[0034] Furthermore, when indoor sound waves are transmitted to the interior wall 8, they first come into contact with the exposed surface of the interior wall 8. Since the exposed surface is composed of multiple wedge-shaped structures 12, these wedge-shaped structures 12 can increase the path of the sound waves and prolong the propagation time of the sound waves on the surface of the interior wall 8, thereby enhancing the sound absorption effect. The sound waves are reflected and absorbed multiple times on the surface of the wedge-shaped structure 12. The geometry of the wedge-shaped structure 12 helps to disperse the energy of the sound waves, causing them to undergo multiple reflections and refractions in the structure, and gradually be absorbed by the material of the interior wall 8, reducing the reflection and transmission of noise. Through the design of the wedge-shaped structure 12, the sound absorption performance of the interior wall 8 is significantly improved, which can more effectively reduce the reflection and transmission of indoor noise, thereby achieving a better sound insulation effect.

[0035] In one specific example, the hollow layer 6 is a hollow structure surrounded by a sealing isolation strip 13.

[0036] Specifically, the hollow layer 6 is surrounded by a structure of sealing isolation strips 13. This design gives the soundproof wall 1 good sealing and isolation performance in the hollow layer 6. The sealing isolation strips 13 can be made of rigid or elastic materials, which can effectively isolate the propagation of sound waves, thereby improving the sound insulation effect. The hollow structure formed by the sealing isolation strips 13 effectively prevents sound waves from propagating through the wall, reduces the transmission and diffusion of sound, and improves the sound insulation performance of the soundproof wall 1. The sealing isolation strips 13 of the hollow layer 6 form a stable structure, which helps the overall strength and stability of the wall, especially in maintaining a stable sound insulation effect when facing changes in the external environment.

[0037] In a specific example, the thickness of the sponge layer 4 is the first thickness, the thickness of the glass layer 5 is the second thickness, the thickness of the hollow layer 6 is the third thickness, and the thickness of the foam layer 7 is the fourth thickness. When viewed from the angle of cross-section along the width of the sound insulation layer 3, the ratio of the first thickness, the second thickness, the third thickness, and the fourth thickness is 1:2:3:2.

[0038] Specifically, the sponge layer 4 is located on the surface of the soundproof wall 1 facing the interior. The sponge layer 4 has the ability to absorb sound waves, reduce sound reflection and propagation, and improve the sound insulation effect. Its open structure can effectively capture and dissipate sound wave energy. The glass layer 5 is closely attached to and fixedly connected to the back of the sponge layer 4. The glass layer 5 provides structural support and sealing for the soundproof wall 1, and at the same time, it acts as a sound wave isolation layer to prevent sound from penetrating the wall. The hollow layer 6 is a structure surrounded by a sealing isolation strip 13. The hollow layer 6 effectively isolates the propagation of sound waves through the sealing isolation strip 13, improving the overall sound insulation effect. It also enhances the structural stability and durability of the soundproof wall 1. The foam layer 7 is closely attached to and fixedly connected to the back of the hollow layer 6. The foam layer 7 provides additional sound insulation performance. Its material density and structural design help reduce sound wave propagation and the resonance effect of the wall.

[0039] Furthermore, by designing the thickness of different layers in a ratio of 1:2:3:2, the soundproof wall can evenly handle sound waves of different frequencies, ensuring efficient sound insulation. The thickness ratio of each layer optimizes the physical properties of the wall, enabling it to not only have good sound insulation but also maintain structural stability and durability. Through a reasonable thickness ratio design, material costs can be controlled while achieving efficient sound insulation, providing an economical solution.

[0040] In one specific example, the inner end face 11 is coated with a sound-insulating coating 14.

[0041] Specifically, the sound-insulating coating 14 applied to the inner end face 11 is a coating specifically designed to reduce noise transmission. This coating can be applied to the inner end face 11 of the soundproof wall 1, i.e., the side facing the interior. The sound-insulating coating 14 can further enhance the sound insulation effect of the wall, especially in terms of mid-to-high frequency noise. It can absorb the energy of sound waves and reduce the propagation of sound waves through the wall. The sound-insulating coating 14 can reduce the resonance effect of the wall and prevent the vibration caused by sound waves inside the wall from being transmitted to other parts. The sound-insulating coating 14 can usually be sprayed or brushed, making it easy to apply and suitable for different types of building walls. When sound waves are transmitted to the inner end face 11 of the soundproof wall 1, the sound-insulating coating 14 can effectively absorb some of the sound wave energy, reduce sound wave reflection and propagation through the wall. Through its material properties, the sound-insulating coating 14 further blocks the transmission of sound waves, thereby enhancing the overall sound insulation effect.

[0042] In one specific example, the outer end face 10 is provided with a waterproof membrane 15 on the contact surface with the outer wall 9.

[0043] Specifically, the waterproof membrane 15 is a waterproof material applied to the part where the outer end face 10 of the soundproof wall 1 contacts the outer wall 9. Its main function is to prevent moisture from entering the interior of the wall, protecting the wall structure and its materials. The waterproof membrane 15 can effectively prevent rainwater and moisture from entering the interior of the wall, avoiding damage to the wall materials due to dampness, extending the service life of the wall, preventing moisture from entering the interior of the wall, avoiding the decline in sound insulation performance caused by moisture, and ensuring that the soundproof wall 1 maintains a good sound insulation effect for a long time. The waterproof membrane 15 can prevent the growth of mold caused by a damp environment, protecting the hygiene and safety of the wall. The waterproof membrane 15 is set at the part where the outer end face 10 of the soundproof wall 1 contacts the outer wall 9, forming a waterproof barrier. When there is rain or moisture outside, the waterproof membrane 15 can effectively prevent moisture from entering the interior of the wall, protecting the wall materials from the effects of moisture. The waterproof membrane 15 ensures that the interior of the wall remains dry, thereby maintaining the performance of the sound insulation material and the structural stability of the wall.

[0044] In one specific example, the exposed surface of the exterior wall 9 is coated with a weather-resistant coating. 16

[0045] Specifically, weather-resistant coatings are coatings that can resist the effects of various climatic conditions (such as ultraviolet rays, rain, wind, and sand) on building materials. They are applied to the exposed exterior surfaces of soundproof walls, directly facing the external environment. Weather-resistant coatings resist ultraviolet radiation, preventing wall materials from aging, fading, or deteriorating due to long-term exposure to sunlight. The coating effectively prevents rainwater and moisture from entering the wall, avoiding dampness, mold, or damage. The coating resists wind and sand erosion, protecting the wall surface from wear and corrosion, thus providing comprehensive protection. The weather-resistant coating can extend the service life of the soundproof wall 1, maintaining its long-term aesthetics and stable performance. The surface of the weather-resistant coating is smooth, easy to clean and maintain, reducing the maintenance cost of the wall. The weather-resistant coating is applied to the exposed surface of the exterior wall 9, forming a protective film. When the external environment (such as sunlight, rain, wind and sand) acts on the wall, the weather-resistant coating can effectively block and resist the erosion and damage of these factors to the wall. The coating keeps the wall surface dry and clean, and prevents ultraviolet rays from damaging the material, ensuring the long-term stability of the wall structure and sound insulation performance.

[0046] In one specific example, the sponge layer 4 is a polyurethane sponge with an open-cell structure.

[0047] Specifically, the open-pore structure means that the sponge has many interconnected pores inside. This structure can effectively absorb and weaken the propagation of sound waves. The open-pore structure increases the surface area of ​​the sponge, making it more effective at absorbing sound waves, thereby reducing noise reflection and propagation. Polyurethane material itself has good sound absorption properties, and the open-pore structure further enhances this effect. The open-pore structure of the sponge has good air permeability, which can prevent the accumulation of internal moisture, helping to keep the material dry and maintain long-term performance stability. Polyurethane sponge is lightweight, which can reduce the overall weight of the soundproof wall 1, making it easy to install and maintain. Polyurethane material has good durability and anti-aging properties, which can maintain its sound absorption effect and physical properties for a long time. When sound waves reach the sponge layer 4, the open-pore structure of the polyurethane sponge can absorb and weaken the energy of the sound waves through its pores, reducing the reflection and propagation of sound waves. The open-pore structure further reduces the sound wave energy by increasing the complexity of the sound wave propagation path, thereby achieving a better sound insulation effect. The sound absorption effect of polyurethane sponge is not limited to high-frequency noise, but also has a significant absorption capacity for mid- and low-frequency noise.

[0048] The soundproof wall 1 provided above effectively utilizes the sound absorption and sound insulation properties of different materials by optimizing the combination of multi-layer materials and structural design, thereby enhancing the overall sound insulation effect. At the same time, it solves the problems of complex installation, high cost and material aging in the existing technology, and significantly improves the application performance in places with high sound absorption standards.

[0049] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
